MOP.

Specification of Letters Patent.

Patented May a, reis.

To all whom t may concern.'

Be it known that I, BALsER HARK, a citi- Zen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Mops; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use theV same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to mops, and more particularly to means for clamping a mop head to its stick; the principal object of the invention being to provide an adjustable device of this character, whereby the head may be easily and quickly applied to the stick, and which will securely hold the parts together when they are assembled. In accomplishing this object, I have provided the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein:

Figure I is a perspective view of a mop constructed in accordance with my invention. Fig. II is an enlarged vertical section of a portion of the same. Fig. III is a plan view of the clamp and ferrule. Fig.

IV is a similar view of a modified form of clamping device. Fig. V is an elevation of the same. Fig. VI is a plan view of another modified form of clamping device. Fig. VII is a similar view, showing the clamp in open position.

Referring more in detail to the parts: 1 designates a mop stick of ordinary design, having a ferrule 2 rigidly secured to one of its ends by a nail 3. The ferrule is formed of metal and comprises a tubular neck 4c, which is adapted for application to the end of the mop stick, and a concave, preferably oval flange 5; the latter being provided with downwardly and outwardly inclined, elongated bosses 6 on its upper surface, having elongated apertures 7. Loosely mounted in the apertures 7 is a clamp bar 8, which comprises a U-shaped rod, having a slightly curved base 9 and upwardly and outwardly inclined side members 10, one of which is provided with an outwardly turned hook 11 that rests on the upper face of one of the bosses 6, and the other being provided with screw threads 12 for receiving a nut 13.

Covering the concave face of the flange 5 and projecting beyond the edges thereof, is a rubber, or like washer, 14 through which the clamp bar 8 projects and against which a bunch of string or yarn is placed in such a manner that when it is engaged by the 4clamp' bar 8, the string or yarn is drawn against the rubber washer and into the concaveface of the ferrule, thereby spreading the strands and rounding the body to form a symmetrical mop.

As a modilication of the above described structure, I have shown (Figs. IV and V) a ferrule having a round flange 16 and a clamp bar 17 similar to the bar 8, except that both the free ends are threaded to receive nuts 13. This form of clamp permits a wider range of adjustment and is preferably used in making large mops in which a greater quantity of string or yarn must be compressed.

Still another form of clamp is shown (Figs. VI and VII) in which one of the free 4ends of the clamp bar is provided with a cross head 18, which may be inserted in the slot 7 as clearly shown in Fig. VII; the other end being provided with a nut 13, so that when the bar is turned and the threaded end inserted in the other slot 7, the nut may be tightened to spread and hold the string in place.

In assembling the mop, presuming the parts to be constructed as described, a bunch of string or yarn is cut to the required length and the U-shaped clamp bar 8 placed around the middle portion. The hook 11 is then inserted in one of the apertures 7 and the bar revolved, so that the threaded end 12 enters the other aperture?, in which position the nut 13 is screwed on the shank to draw the string against the rubber washer and into the concaved portion of the ferrule to spread the strands and round out the body of the mop.

It is apparent that by inclining the bosses 6 and the free ends 10 of the U-shaped clamp bar 8, as the bar is drawn up by the nut the string is crowded more to the center of the ferrule, so that the slightly curved base 9 of the bar will coact with the concave surface of the flange 5 to round out the body of the mop. It is also apparent that with the rubber washer 14e extended beyond the flange 5, there is no danger of the metal flange scratching floors or objects against which the mop is brought in vContact, because the edge of the flange 5 is entirely protected. I

While I have described and illustrated my invention as applied to mops, it is to be understood that the same can be applied to clusters, and the like without departing from the scope of the invention.

I-Iaving thus described my invention, what I claim as new therein, and desire to secure by Letters-Patent, is:

l. The combination with a handle, of a ferrule on said handle having a bell-shaped head provided with alining transverse slots, a U-bolt having its ends located in said slots, means on the ends of the U-bolt for locking In testimony whereof I affix my signature l in presence of two witnesses.
